Amazon Elastic Block Store (Amazon EBS) is intended for use in conjunction with Amazon's Elastic Cloud (EC2) instances.
Last June, Amazon unveiled the new SSD-backed volume type for EBS, boasted to offer 99.999 percent availability. The General Purpose SSD was designed for productivity in small to medium-sized databases, in test and development environments as well as boot volumes.
Thus, customers can choose between three different EBS volume types: General Purpose SSD, Provisioned IOPS SSD, and Magnetic volumes.
As outlined in November, the General Purpose SSD option now supports volumes up to 16TB and up to 10,000 IOPS and 160MBps throughput. The high-performance Provisioned IOS SSDs supports up to 16TB volumes and 20,000 IOPS and 320MBPs.
